Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, and in particular to a high-efficiency welding device for steel structures and a process thereof. Background Art

[0002] Steel structure welding is a method of combining steel parts at the atomic level by heating, pressurizing or a combination of both. It is an indispensable key process in the fields of building structures, bridge construction, and machinery manufacturing. Its core goal is to connect different metal components to build a stable overall structure. This process usually involves the melting of local areas of the welding rod and / or the workpiece surface and subsequent cooling and solidification to form a high-strength joint.

[0003] Currently, before welding steel structures, operators are required to manually adjust the position between the connecting steel and the welding steel until the welding position is aligned, in order to ensure the quality and safety of the subsequent finished products. At the same time, during the welding process, it is necessary to ensure that the welding effect is uniform and stable, and the welding position is accurately guaranteed by constantly adjusting the position of the welding gun and its distance from the welding point. It can be seen that these preliminary preparations and real-time control steps are crucial to ensuring welding quality and structural strength. However, due to the cumbersomeness of the calibration and adjustment process, the time cost for each welding point is increased, thereby reducing construction efficiency.

[0004] Therefore, in order to meet this challenge, it is necessary to develop a high-efficiency welding device for steel structures and its process, aiming to simplify the welding preparation work and optimize the welding process to improve work efficiency. Summary of the invention

[0010] Furthermore, it also includes a guide rod, and the sliding rod is provided with insertion holes arranged at intervals. A group of guide rods is arranged at the bottom of the guide sleeve. A clamping seat is slidably arranged between the guide rods in the same group. The clamping seat slides through the guide sleeve on the same side, and the clamping seat is inserted and matched with the insertion hole on the same side. An elastic member three is also arranged between the clamping seat and the corresponding guide rod.

[0011] Furthermore, it also includes a laser rust removal machine. A laser rust removal machine is respectively arranged on both sides of the annular guide rail for rust removal of the connected steel.

[0028] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0029] In addition, the terms "first", "second" and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. It should be noted that the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Embodiment: A high-efficiency welding device for steel structure, such as Figure 1-Figure 5 As shown, including: Support rod 1 is a horizontally placed mounting carrier; There are two rodless cylinders 2, which are fixedly mounted on the left and right ends of the support rod 1, and the rodless cylinders 2 tend to extend downward as a whole. A cross bar 21 is arranged between the sliders of the rodless cylinder 2, and an electric bidirectional screw 22 is fixedly mounted on the cross bar 21. The electric bidirectional screw 22 is composed of a motor and a bidirectional screw. A clamping plate 23 for clamping and connecting steel is symmetrically slidably arranged on the cross bar 21. The clamping plates 23 on both sides are respectively threadedly connected to one side of the bidirectional screw of the electric bidirectional screw 22, so that the clamping plates 23 on both sides can slide away from or approach each other along the corresponding threads. An extension plate 24 extending outward is also fixedly arranged on the side of the slider of the rodless cylinder 2 away from each other, and an auxiliary wheel frame 25 for assisting displacement is connected to the extension plates 24 on both sides; Specifically, see Figure 3 The support rod 1 serves as the main bearing platform and can also serve as the operator's holding platform. The rodless cylinder 2 is used to realize the lifting drive, which can drive the cross bar 21 and the components carried on the extension plate 24 to operate synchronously. When it is necessary to clamp the connecting steel, the lifting function of the platform can be used to quickly locate and clamp the steel. Through the action of the electric two-way screw rod 22, the clamping plate 23 can quickly adjust its position to complete the clamping action and ensure that the clamped object can always be in the center position. After completing the grabbing of the connecting steel, the auxiliary wheel frame 25 can be used. It can be horizontally mounted on the main welding steel through its length advantage. Subsequently, the clamping plate 23 is adjusted again through the electric two-way screw rod 22 to accurately adjust the tightness of the connecting steel, thereby facilitating the subsequent adjustment of the welding position. This method not only simplifies the adjustment process of the welding position, but also makes the entire operation simpler and faster to improve work efficiency.

[0031] The annular guide rail 3 is arranged at the front side of the support rod 1. A gear ring 31 is rotatably arranged in the annular guide rail 3. An electric gear 32 is symmetrically installed on the top of the annular guide rail 3. The electric gear 32 is composed of a motor and a driving gear. The driving gear of the electric gear 32 passes through the annular guide rail 3 and meshes with the gear ring 31 to drive the gear ring 31 to rotate. The assembly frame 4 is arranged on the gear ring 31, and an adjusting rod 41 is slidably arranged on the front side of the assembly frame 4. The adjusting rod 41 slides in the up and down directions. A welding gun 42 is arranged between the upper and lower ends of the adjusting rod 41, and an elastic member 43 sleeved on the adjusting rod 41 is arranged between the bottom of the welding gun 42 shell and the assembly frame 4. In this embodiment, the elastic member 43 is a spring.

[0032] Specifically, the gear ring 31 is driven to rotate by the electric gear 32, so that the welding gun 42 installed on the gear ring 31 can achieve 360-degree circumferential movement around the steel, thereby quickly completing the welding operation. At the same time, the sliding function of the adjustment rod 41 and the adjustable setting of the elastic member 43 ensure that the welding gun 42 always maintains a longitudinal downward state, ensuring that the muzzle of the welding gun 42 is quickly and accurately aligned with the welding point. In addition, the lifting and adjustment ability of the rodless cylinder 2 makes the position adjustment of the welding gun 42 more flexible. It can be seen that this design not only provides great convenience for operation, but also makes the entire process more automated and convenient compared to the traditional handheld welding gun operation method, greatly improving the stability and efficiency of the operation.

[0033] From this, in summary, this device integrates multiple functions such as clamping positioning, auxiliary movement, lifting adjustment, position calibration and fast operation, aiming to optimize the operation process in traditional steel structure welding operations. By centrally processing various operations before and after welding, it not only improves the continuity and convenience of operation, but also provides higher efficiency for steel structure welding; in this way, the entire operation process becomes smoother and more efficient, meeting the needs of current welding operations.

[0034] like Figure 5 As shown, a fitting wheel 44 is also included. The bottom of the shell of the welding gun 42 is provided with a fitting wheel 44 for assisting the welding gun 42 to fit the steel material for welding and moving, thereby supporting and assisting in adjusting the welding gun 42.

[0035] like Figure 1 , Figure 6 and Figure 7 As shown, a mounting frame 5 is also included. The mounting frames 5 are fixedly arranged on the left and right sides of the inner side of the gear ring 31. Motors 51 are installed on the mounting frames 5. The motors 51 are connected to the driving shafts 52. The driving shafts 52 pass through the corresponding mounting frames 5 and the two are rotatably matched. A wire wheel 53 is slidably arranged on the shaft end of the driving shaft 52. An elastic member 54 is arranged between the wire wheel 53 and the mounting frame 5 on the same side. In this embodiment, the elastic member 54 is a spring.

[0036] Specifically, the motor 51 drives the corresponding driving shaft 52 to rotate, thereby driving the wire wheel 53 connected thereto to rotate synchronously. Since the wire wheel 53 and the driving shaft 52 are connected by sliding connection, and under the action of the elastic member 54, the wire wheel 53 can move back and forth reciprocatingly. This mechanism ensures that the welding slag on the steel can be effectively scraped off during the welding process. In addition, a rotatable end cover is provided at the front shaft end of the wire wheel 53 (see Figure 7 ), this allows the wire wheel 53 to quickly adapt to changes in the contact surface when cleaning the steel angle. Through the synergistic effect of sliding position adjustment and rotating end cover, the wire wheel 53 can accurately and tightly fit the working surface in more occasions, thereby improving the accuracy and applicability of the cleaning effect.

[0037] like Figure 8 As shown, it also includes a guide sleeve 6. A guide sleeve 6 is provided on each side of the clamping plates 23 that are away from each other. A sliding rod 61 is slidably inserted through the guide sleeve 6. An extension plate 62 is provided at the rear end of the sliding rod 61 to increase the clamping area of ​​the clamping plate 23.

[0038] like Figure 8 As shown, it also includes a guide rod 63, and the sliding rod 61 is provided with holes 611 arranged at intervals. A group of guide rods 63 is arranged at the bottom of the guide sleeve 6, and the number of a group of guide rods 63 is two. A clamping seat 64 is slidably arranged between the two guide rods 63 in the same group. The clamping seat 64 slides through the guide sleeve 6 on the same side to fix the sliding rod 61, and the clamping seat 64 is inserted and matched with the hole 611 on the same side. An elastic member three 65 is also arranged between the clamping seat 64 and the corresponding guide rod 63. In this embodiment, the elastic member three 65 is a spring, which can provide the clamping seat 64 with the elastic force required for resetting. Through the coordinated work of various components, the clamping seat 64 can be smoothly inserted into the hole 611 on the sliding rod 61 after the position is adjusted, thereby realizing a stable position locking, and providing a more reliable clamping effect.

[0039] like Figure 1 and Fig. 9 As shown, a laser rust remover 7 is also included. A laser rust remover 7 is respectively arranged on the left and right sides of the annular guide rail 3. The laser rust remover 7 is equipped with a rotating laser output head. This design can greatly expand the coverage of laser scanning rust removal through rotation operation, making the whole particularly suitable for rust removal before steel connection, ensuring that the pretreatment work before welding becomes more efficient.

[0040] Based on the above-mentioned high-efficiency welding device for steel structure, a high-efficiency welding process for steel structure includes the following steps: S1. The operator holds the support rod 1 and starts the rodless cylinder 2 to drive the crossbar 21 and its upper parts to rise and fall together. When the clamping plate 23 moves to the place where it connects to the steel, the electric bidirectional screw 22 is started to drive the clamping plates 23 on both sides to approach the steel until the clamping plates 23 clamp and fix the steel. Then, the sliding rod 61 is pushed and the extension plate 62 is pushed out to increase the clamping contact area between the clamping plate 23 and the steel. S2, place the two steels for main welding on the placement platform, then place the entire device on the main steel, use the auxiliary wheel frame 25 to provide support and assist the movement of the device, ensure that the welding part of the connecting steel is in contact with the main steel, then start the rodless cylinders 2 on both sides again, adjust the muzzle position of the welding gun 42 to calibrate the welding position; S3, start the laser rust removal machine 7 to remove rust from the surface of the connected steel; S4, start the electric gear 32, drive the gear ring 31 to rotate on the annular guide rail 3, the fitting wheel 44 rotates close to the connecting steel, the welding gun 42 rotates accordingly, and is aimed at the welding position for welding, and then synchronously start the motor 51, drive the wire wheel 53 to rotate, and synchronously scrape the welding slag on the surface of the steel; S5. After the welding of one end of the steel material to be connected is completed, the device direction is changed, and the connecting steel material is clamped again in combination with the above operation, so that the other end of the connecting steel material is fitted with another main steel material to carry out another part of the welding operation.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
